BREAKING: Magnitude-4.2 Earthquake Shakes LA Region

A magnitude-4.2 earthquake shook the Los Angeles area on Sunday night.

The epicenter was reported at 7:36 p.m. PDT, four miles west-northwest of Westwood, California, the United States Geological Survey said. It was initially rated as a magnitude-3.7 earthquake and then a 3.8, but was later upgraded to a 4.2.

No significant damage was reported, according to Firefighter Erik Scott, a spokesman for the Los Angeles Fire Department. The department conducted a damage survey of its 470-square-mile area.

The temblor was felt throughout the region, according to the USGS website.

The Pittsburgh Pirates were playing the Los Angeles Dodgers at Dodger Stadium at the time of the quake. Pirates broadcasters Greg Brown and John Wehner said on KDKA-FM that they didn't feel the quake.

There were no initial reports of injuries, KABC-TV in Los Angeles reported.

Right after the Westwood quake, two other quakes were reported in the area, the USGS said. A magnitude-1.8 quake occurred near Topanga, and the second quake, a 1.6 magnitude, was reported near Santa Monica.
